Abstract

The scaffolding strategy is a strategy that makes students more active in learning by providing step-by-step assistance from teachers and peer tutors so that it can influence student’s science process skills. The scaffolding strategy also makes learning in class more active because students are more confident in voicing their opinions. Implementation of the scaffolding strategy by providing assistance at the student learning stage, so that students can influence students' science process skills.The method that will be used in researching student workseet assisted scaffolding is a quasi-experimental method with a non-equivalent control group pretest-posttest design, which divides the research sample into an experimental group and a control group. The data in this study was obtained based on the results before the test, results after the test, observation sheets on learning implementation, and documentation.

Abstract

In this study, Nickel layers were deposited on a Tungsten Carbide (WC) substrate using pulse current densities of 0.35 and 0.4 mA/mm2. The Nickel deposition was performed by electrodeposition for 30 minutes at a temperature of 40°C with a stirring rate of 600 rpm. Based on the SEM characterization results, the Nickel layer at a magnification of 1000x showed that at a current density of 0.35 mA/mm2, the particle distribution was uniform, with no cracks or agglomeration on the substrate surface, and the particles were larger and more homogeneous. In contrast, at a current density of 0.4 mA/mm2, the particle distribution was less uniform, there were no cracks or agglomeration on the substrate surface, and the particles appeared smaller and homogeneous, resulting in a smoother Nickel layer surface. The EDS scanning results indicated the successful formation of the Nickel layer, with the presence of Ni metal content, which increased with the current density from 0.35 to 0.4 mA/mm2.

Abstract

The teacher is a moral agent, Maslow’s hierarchy of needs which ends in self-actualization is proven to be unable to bring individuals to find their identity. Problems arise when teachers are oriented towards the love of creatures, material or power. Parennialism with the concept of universal divinity, lowers the perception that the mechanism of the universe including humans can be explained through the nature of matter and energy. A consistent scientific model was found after analyzing the phenomena experienced by the key informant, namely a teacher who proceeded from the initial level to the peak of self-transcendence through the discovery of ‘meaning’. His awareness was instilled through an auto-suggestion pattern, then the key informant was guided to find out the biggest negative energy that moved him. The teacher is likened to the property of a particle insulated by a spin magnitude, and the location of the valence electrons with the greatest energy in the uncertainty region is indicated by the electron configuration. Initially fana al-nafs (0), matter (neutrons) is fissioned until meaning is found as energy, the magnitude of meaning energy (E) depends on how many reactions there are, then and c is the velocity of emission of β particle was constant in terms of the moment of inertia. Like the stability of heavy atomic nuclei after fission can be recovered by releasing β particle emissions, with a ratio of neutron (N) and proton (Z) namely . Surrender leads to the concept of no god (0) but God (1).

Abstract

A theoretical study has been conducted on stochastic differential equations for both linear and nonlinear Geometric Brownian Motion, focusing on deriving the Probability Density Function (PDF) and its characteristics. The research is purely theoretical. The study involved formulating stochastic differential equations for both linear and nonlinear Geometric Brownian Motion. The solution for the probability density function of Geometric Brownian Motion was obtained using the Fokker-Planck equation, which corresponds to its stochastic differential equation. Linear Geometric Brownian Motion with a constant drift term does not yield a probability density function that is valid for all x and t. In contrast, nonlinear Geometric Brownian Motion can have a probability density function valid for all x and ttt under certain conditions.

Abstract

Radiographic contrast is the difference in brightness in a film image, due to differences in the object's absorption capacity for X-rays, which affects the quality of the radiographic image. Gray value is a substitute for the density of conventional radiographic film which is viewed and evaluated using a computer, to obtain a visual perception of image contrast and noise to measure the quantity of radiation that penetrates a certain area. Acceptance Value Minimum X-ray density refers to ASME Standards. The CRx gray value is 28800 minimum and 64000 maximum [1]. In the use of the Betatron Sea-7 machine, to obtain radiographic contrast, it is necessary to add aluminum (Al) or stainless steel (SS) as a filter layer. The method involves irradiating a steel material target with a thickness of 25 mm with 5 MeV energy with a dose of 35 R, either using or without a layer of Al or SS material, then analyzed using the Rhythm Review Application. The results obtained, for stainless steel, the density received at a thickness of 3 mm, 6 mm, and 9 mm, for aluminum a thickness of 3 mm. With this energy and dosage, stainless steel can be added as a layer in the operation of the Betatron Sea-7 machine to produce a radiographic film quality density that meets ASME standards [2].
